Built from the chassis of the redesigned RS, the all-new RX 80 W LV offers a racing pedigree with enhanced women-specific features and a new, more inclusive fit. Lange's new Dual Core shell construction and Dual 3D liner integrate perfectly, ensuring unparalleled foot-wrapping, precision, and power transmission. The new RX specific fit retains Lange's strong heel lock and foot hold with more instant "out-of-the-box" comfort.
